Abstract (en)
[origin: EP3118272A1] Problem To provide a technique having high industrial practicality for providing a transparent conductive coated film that is excellent in conductivity, light transmissibility, haze characteristics, and adhesiveness. Solution A method for producing a silver nanowires ink, containing adding a viscosity modifier and a water-soluble acrylic-urethane copolymer resin, to an aqueous solvent or a mixed solvent of water and an alcohol having silver nanowires dispersed therein. The content of the water-soluble acrylic-urethane copolymer resin with respect to the total amount of the silver nanowires ink may be from 0.05 to 2.0% by mass. The content of silver with respect to the total amount of the silver nanowires ink is preferably from 0.05 to 1.0% by mass. The content of the viscosity modifier with respect to the total amount of the silver nanowires ink is preferably from 0.01 to 1.0% by mass. The viscosity of the silver nanowires ink is preferably controlled to a range of from 1 to 100 mPa·s.
